System and method for real-time processing of compressed videos

A method for displaying video on a display by a real-time video processing device comprising a processor and a memory containing non-transient instructions that, when executed by the processor, comprise the steps of:

• receiving compressed video data;
• decoding the compressed video data to produce an uncompressed first video frame, a first frame syntax element, an uncompressed second video frame adjacent to the first video frame in a video sequence, and a second frame syntax element;
• applying a first video enhancement process to the uncompressed first video frame to produce an enhanced first video frame having a higher resolution than the uncompressed first video frame;
• applying a second process to the uncompressed second video frame to produce an enhanced second video frame, further comprising the steps of:
• adaptively transferring a block comprising a portion of the enhanced first video frame from the enhanced first video frame to the uncompressed second video frame according to the first frame syntax element and the second frame syntax element to produce the enhanced second video frame having a higher resolution than the uncompressed second video frame;
• and
• displaying the enhanced first video frame and the enhanced second video frame with the display;
• accumulating a metric for a parameter indicating a computation cost change and/or a quality change between the enhanced first video frame and the enhanced second video frame;
• determining an accumulated metric threshold value;
• and
• comparing the accumulated metric to the accumulated metric threshold, wherein the first video enhancement process is more computationally intensive than the second video enhancement process, and the second video enhancement process leverages an inter-frame similarity between adjacent frames in the video sequence and transfers an enhancement result from the first enhanced video frame to the second enhanced video frame.
